SHORT TERM /THROUGH SATURDAY/

Issued at 135 AM CDT Fri Oct 2 2026

Post-frontal airmass takes over after a prolonged stretch of wet weather, with surface high pressure building over the region. We will see cooler temperatures in the 60s, clear skies, and light northeast winds through the day. Widespread temperatures in the 40s tonight, with light east-northeast winds.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/

Issued at 135 AM CDT Fri Oct 2 2026

Zonal to northwest flow will set up in the upper levels over the weekend with a couple of shortwave troughs coming through Saturday evening and again Wednesday. Low moisture content will mean these frontal passages will be dry with an increase in upper level clouds and a northerly shift in the winds being the main impacts. Otherwise, skies will be mostly clear and winds should remain light with high pressure setting in for the week. Temperatures will be seasonable with highs in the 60s to 70s and lows in the 40s to 50s through Tuesday. The shortwave features on Wednesday will bring some warm air advection from the Desert SW which will increase temps a bit through the later half of the week, with highs in the mid 70s and lows in the mid 50s.

AVIATION /12Z TAFS THROUGH 12Z SATURDAY/

Issued at 630 AM CDT Fri Oct 2 2026

VFR will continue through the period as high pressure builds into the Upper Mississippi Valley region. N to NE winds between 5 to 15 kts can be expected through the day.

HYDROLOGY

Issued at 1231 PM CDT Thu Oct 1 2026

Now that we've seen where most of the rain has fallen and how rivers are beginning to respond, many of the river forecasts have been adjusted downward since yesterday. While all rivers and creeks are responding to the rainfall, we are no longer expecting flooding along the Rock River nor along the Mississippi River. Some of the rivers that do flood may remain above flood stage for several days before receding due to the widespread stratiform nature of this rainfall.
